Thanks to footage from the Metis coronagraph aboard the European Solar Orbiter mission, an international team coordinated by Italian researchers has been able to observe the propagation of turbulent motions in the solar wind from the innermost parts of the Sun's corona to space. Knowledge of the mechanisms that drive the evolution and propagation of these phenomena in the solar wind will help improve predictions about the potential impact it may have in our planetary system and especially on Earth. The study, in which researchers from ASI, CNR and the Universities of Florence, Padua, Urbino, Genoa, Catania, Palermo and Calabria collaborated, was published in the Astrophysical Journal Letters. The footage obtained by the European Space Agency's Solar Orbiter mission thanks to the Metis coronagraph designed by the National Institute of Astrophysics (INAF), University of Florence, University of Padua, CNR-IFN, and built by the Italian Space Agency with the collaboration of Italian industry, confirms something long suspected: the turbulent motion of the solar wind begins very close to the Sun, within the portion of the solar atmosphere known as the corona. Small disturbances that affect the solar wind in the corona are carried outward and expand, generating turbulent flow farther out into space.
